Question

Part 2 out of 2If you plan to cancel your internet service after 11 months, which is the cheaper option

Answer 1

m = number of months

Option 1 cost = 35 + 20m

Option 2 cost = 25m

Part 1: If the cost is equal for both otpions, then we can write: 35 + 20m = 25m, solving for m:

5m = 35 ==> m = 35/5 = 7

m = 7

In month 7, the cost is 35 + 20(7) = 35 + 140 = 175

Part 2:

Option1 cost when m = 11: 35 + 20(11) = 35 + 220 = 255

Option2 cost when m = 11: 25(11) = 275

Option 2 costs more than option 1, so Option 1 is cheaper
